Aaron knows that Marcellus's daughter and Owen are in the same kindergarten, and Aaron's control over Katrina has become more domineering in the same class.
He's afraid to encounter the situation on the day of the admission ceremony again, that is, Katrina and Marcellus's opportunity to come into contact alone.
So since that day, Aaron has refused Katrina to go to kindergarten alone.
When they go out, Aaron sends Owen to kindergarten first, then Katrina to the police station.
After work, Aaron will pick up Katrina from the police station and then Owen from school.
He is happy to repeat such work every day, looking after his wife and not giving anyone a chance.
Especially when meeting Marcellus, who sends her daughter to school at the kindergarten gate, Aaron puts his arms around Katrina's waist, greeting Marcellus with a graceful smile.
Aaron's exaggeration makes Katrina feel at a loss whether to cry or to laugh.
